I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

None of the airplane features were available during the flight.

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Getting to the flight was arduous and lengthy. The flight itself was good but the food option wasn’t a good selection. I need to do a Kosher option on my return. Flight crew were nice

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

Some of the Air hostesses are not that friendly. Need improvement

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

horrible service, food was an embarrassment, no charging for cellphones, stay away

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

we were missing our luggage, trying to find someone to have any empathy was pretty much not happening....

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

Not comparable to Qatar Airways services on flights to Doha. Flight attendants provided basic services; I was never recognized by name or as an Executive Platinum member. Restrooms were not kept clean during the flight.

Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative

it was fine, decent flight... dont get food besides cookies or pretzels so not sure why you ask about food. same for entertainment..

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

I got sick nothing contagious but distressing enough and the care I received on the flight was astounding.

Waaay too small plane. They also need to up the size of the overhead bins. I would love to keep me 3k with of camera equipment in my hard case baggahe instead of it being thrown into the belly of the plane
